Larry Jordan's terific close up photo of his Pinkspotted Shrimp Goby or Singapore Shrimp Goby (Cryptocentrus Leptocephalus).

The entertaining Shrimp Gobies derive their name from their unusual behavior of sharing their burrows in the sand with various small shrimp, such as the Pistol Shrimp. These Gobies warn their shrimp room mates (which have poorer eyesight) of approaching danger in time for them both to retreat into their burrow.

In return, the shrimps share their food with the Gobies.

Thinking about adding a Goby to your tank? See the Saltwater Aquarium Fish Compatibility Chart first.
